Specification of Letters Patent.

To all whom it may concern."

Be it known that I, DAVID W. HUDSON, a citizen of the United States of America, residing at Green Bay, in the county of Brown and State of Wisconsin, have invented-certain new and useful Improvements in Paper Cutting and Folding Machines, of which the followin isa specification, reference being had therein to the accompanying drawing.

The invention relates to apaper cutting and folding machine where paper napkins are cut from a roll of paper in predetermined length, folded twice, and delivered to a container or the like for further purposes. The principal object of the invention con sists 1n the provision of a machine of the character describedwhich cuts and folds the.

paper napkins and delivers the same to a containerin a novel and efficient manner.

A further object of the invention consists in the provision of improved feeding means, whereby the napkins are conveyed to a container. I

A further object of the invention resides in the provision of a plunger which at a given moment removes the napkins from the feeding means and forces them into the container.

To the accomplishment of the general objects stated and others that will appear as the description proceeds the preferred embodiment of the invention consists in the novel arrangement and construction of parts illustrated in the drawings, described in the specification and defined in the appended claims. In the drawings- Figure 1 is a front elevation of the machine made in accordance with the invention.

Fig. 2 is a rear view of the same.

Fig. 3 is a sectional view taken on line A-A of Fig. 1.

Figs. 4, 5 and 6 show the different positions of the mechanism and of the web of paper.

Fig. 7 is a plan view of the receiving container, plunger and staggered belts for conveying the paper web.

Referring to the drawings 1 designates suitable side frames placed apart and interconnected at their lower end by transverse rods 2 fastened to said frames in any appropriate or suitable manner. The upper ends .The folded of the said frames are connected by the transverse beams 3 which at one side extend beyond the side frame 1 and form supporting arms 4. The arms 4 are formed integral at the outer end with open bearings 5 to receive a shaft 6 upon which a roll of paper 7 is mounted. The transverse arms revolubly support two rollers 8, 9 extending parallel to the roll of paper and at a distance there from to guide the paper web, as will be hereinafter more fully described. The roller 8 is provided at one end with a sprocket wheel 10 which is in alinement with .a subjacently arranged sprocket wheel 11 of a stub sha 12 which by means of the gearing 13 is driven from the main drive shaft 14. As is obvious from Figs. 1 and 3 a sprocket chain 15 is trained around thewheels 10 and 11 whereby rotation is imparted to the roller 8. on the opposite end-of said roller 8 a gear 16 is provided meshing with a similar gear 17 of roller 9. Thus it is seen that upon rotation of the main drive shaft 14 rollers 8 and 9 are driven in opposite direction.

The paper is unwound from the roll 7 and is fed to the rollers 8, 9, such that it contacts with the lower side of the roller 8 and passes over the upper side of the roller 9 to the folder 18 and thence to the feed rollers 19, 20 fast to the shafts 21, 22 respectively, which are journaled in the side frames 1 and driven by gears 19 from the main drive shaft 14. aper passes between said feed rollers and is engaged by the subjacently arranged cutting rollers 23 and 24, the former being mounted on the main drive shaft 14 whilethe latter is fast to a shaft 25 further travel the paper passes between another pair of rollers 28, 29 and is deflected by a slantingly disposed guide plate 80 to contact with the downwardly traveling side of a belt 31 trained around pulleys 32 and 33.

The lower pulley 32 is mounted u on a shaft 34 journaled in the frame m'em ers 1 and driven from the main drive shaft 14 by Patented Oct. as, iota.

suitable connection such as belting. After the paper has reached a position where 1ts center registers with the contact pomt of the pair of rollers 35, 36 arranged in vertical alinement, a tucker blade 37 is caused to o scillate so as to force the paper between said roller 35 and 36, where it receives the second fold and thus is ready for delivery. The rollers 35, 36 are driven from the main drive shaft 14 by means of the sprocket wheels 70 and the chain 72 trained around said wheels.

.A. gear 73 of the roller 36 meshes with a 47, a raised portion 48 of said disk causing the tucker blade 37 to oscillate and to fold the paper in the aforementioned manner.

A pair of sheaves 49, 50 are arranged subj acently to the rollers 35 and 36 and staggered belts 51, 52 connect respectively said rollers and said sheaves. The belt 52 is guided over an idler 50 to provide for the necessary tension of said belt.

From the foregoing it is obvious that the belts 51, 52 carry the paper from the rollers 35, 36 downwardly until it reaches the point opposite the container 53, as indicated diagrammatically in Fig. 6. A plunger 54 is then caused to move toward the sheet of paper between the belts 51, 52 whereby the paper is forced into the container 53, as is clearly indicated in Figs. 3 and 6. The plunger 54 has a stroke sufficient to pass the end pieces 55 of the container upon entering the same. 'Ihe fore-and-aft movement of the plunger is effected by means of the link 56 pivotally secured to said plunger and articulated to a lever 58 of a rock shaft 60 journaled in the side frames 1. An arm 57 of said rock shaft is pivotally connected to a lever 59 fast to a rock shaft 61 whose arm 62 carries a roller 63 in engagement with a ro tary disk 64 fast to a shaft 66 driven from the main drive shaft 14 by a train of gears. A projecting portion of the disk oscillates the arm 62 whereby the plunger executes a reciprocating movement to force the paper into the container 53. In order to insure smooth operation of the plunger the same is provided with a tongue 67 slidingly fitting in a groove 68 arranged in the bottom of the container 53, as indicated in Fig. 7. The end pieces 55 prevent the stack of folded papers from falling and simultaneously provide a guard for the return side of the belt 52. An angle plate 69 arranged incense at the rear side of the stack supports the same and is gradually pushed to the outer end of the container as the same is being filled up. To insure engagement of the roller 63 and cam disk 64, a spring 76 15 connected at one end to the lever 58 and on its other end to the frame 'so that the plunger 54 is quickly restored to normal position after operation. Similarly a spring 77 is attached to the lever 38 and is connected at its op osite end with the frame. If desired the machine can be built having double capacity to which end the transverse beams are provided with another extenslon 4 at the opposite end to provide for the support of another paper roll 7. It is then necessary to make the feed rollers and cutting rollers of double length and to-install an additional plunger which may be driven from the same shaft.

Referring to Fig. 4 the paper web is shown in a position where it is ready to be folded the second time. Fig. 5 shows the tucker blade in a position where it has forced the paper napkin in engagement with the rollers 35 and 36, while Fig. 6 indicates the folded paper in a position opposite the container 53 whereto it has been conveyed by the staggered belts 51, 52. The following operation comprises the forward movement of the plunger 54 whereby the paper is disengaged from the staggered belts and is forced into the container past the side pieces 55 to contact with the previously de livered folded sections of paper, as indicated in dotted lines in Fig. 7.

From the foregoing description of the parts of the machine it is thought that the operation of the same is rendered suficiently clear to make further description thereof unnecessary. While the preferred embodiment of the invention is shown in the drawings by way of example, it is distinctly to be understood that the inventor does not intend to confine himself to the modification shown, but avails himself of such alterations and modifications as come within the scope of the invention as defined by the appended claims.

I claim:

In a machine for cutting and folding sheets of paper, the combination with conveying means of a receptacle, .aplunger adapted to release the detached sheet. of paper from said conveying means and to force it into said receptacle, said receptacle being provided with a groove, said plunger being formed with a tongue slidingly'fitting in said groove, and means for reciprocating said plunger.
